Under the chain-breaking doctrines, which methods can allow admission of illegally obtained evidence?

• A. Independent source
• B. Inevitable discovery
• C. Attenuation
• D. All of the above

Answer: (D)

When evidence gathered through an illegal search or seizure can still be admitted, it’s because the taint of the wrongdoing has been broken by a recognized exception. Independent source means that the information or evidence comes from a separate, legally valid source that is not influenced by the illegal conduct. If the police uncover the same evidence through that independent path, it can be admitted even if part of the process was tainted.

Inevitable discovery looks at what would have happened anyway. If the evidence would have been discovered by lawful means regardless of the illegal action, the fact that the initial step was unlawful doesn’t bar its admission.

Attenuation focuses on the passage of time and intervening events that weaken the link between the illegality and the evidence. If enough independent factors occur—like time, changes in circumstances, or the defendant’s actions—the connection to the illegal conduct can become too remote to require exclusion.

All three are recognized ways to break the chain between illegality and evidence, so the best answer is that all of the above apply.
